Run-Flat Tires (STS-V) If your vehicle has run-flat tires, there is no spare tire and no tire changing equipment. Run-flat tires can operate effectively with no air pressure for a limited distance and speed. These tires perform so well without any air pressure that a Tire Pressure Monitor (TPM) is used to alert you when there is a low tire condition. {CAUTION: Special tools and procedures are required to service a run-flat tire. If these special tools and procedures are not used you or others could be injured and your vehicle could be damaged. Always be sure the proper tools and procedures, as described in the service manual, are used. To order a service manual see Service Publications Ordering Information on page 7-15. {CAUTION: When the low tire warning light is displayed on the instrument panel cluster, your vehicle's handling capabilities will be reduced during severe maneuvers. If you drive too fast, you could lose control of your vehicle. You or others could be injured. Do not drive over 55 mph (90 km/h) when the low tire warning light is displayed. Drive cautiously and check your tire pressures as soon as you can. See Run-Flat Tires (STS-V) on page 5-65 and Tire Pressure Monitor System on page 5-68, for additional information. Tire Sealant and Compressor Kit Your vehicle has a tire sealant and compressor kit that is capable of temporarily sealing small punctures in the tread. There is no jack or spare tire. The kit inflates the tire with liquid sealant and air. After the tire is inflated to the recommended inflation pressure, see Inflation - Tire Pressure on page 5-66 for more information, the vehicle must be driven for five miles to distribute the sealant in the tire and seal the puncture. After driving five miles the tire pressure must be rechecked and adjusted as needed. See Using the Tire Sealant and Compressor Kit later in this section. 5-87
